Opens a message writer stream and gives it to the block. The stream is valid only in the block, and has these methods:
outputs STR and CR LF.
outputs STR.
outputs sprintf(fmt,*args).
outputs STR and returns the length of written bytes.
outputs STR and returns self.
If a single CR (“r”) or LF (“n”) is found in the message, it is converted to the CR LF pair. You cannot send a binary message with this method.
from_addr
is a String
representing the source mail address.
to_addr
is a String
or Strings or Array
of Strings, representing the destination mail address or addresses.
Net::SMTP.start('smtp.example.com', 25) do |smtp| smtp.open_message_stream('from@example.com', ['dest@example.com']) do |f| f.puts 'From: from@example.com' f.puts 'To: dest@example.com' f.puts 'Subject: test message' f.puts f.puts 'This is a test message.' end end
This method may raise:
The get_attribute_ns
method retrieves a method by its namespace and name. Thus it is possible to reliably identify an attribute even if an XML
processor has changed the prefix.

Writes out text, substituting special characters beforehand. out
A String
, IO
, or any other object supporting <<( String
) input
the text to substitute and the write out
z=utf8.unpack("U*") ascOut="" z.each{|r| if r < 0x100 ascOut.concat(r.chr) else ascOut.concat(sprintf("&#x%x;", r)) end } puts ascOut
Creates windows .bat files for easy running of commands
Creates the scripts to run the applications in the gem.
Return the text for an application file.
Parses a C struct’s members
Example:
require 'fiddle/import' include Fiddle::CParser #=> Object parse_struct_signature(['int i', 'char c']) #=> [[Fiddle::TYPE_INT, Fiddle::TYPE_CHAR], ["i", "c"]] parse_struct_signature(['char buffer[80]']) #=> [[[Fiddle::TYPE_CHAR, 80]], ["buffer"]]
Ensures the root of chain
has a trusted certificate in trust_dir
and the digests of the two certificates match according to digester
Add a certificate to trusted certificate list.
Returns the first element, or the first n
elements, of the array. If the array is empty, the first form returns nil
, and the second form returns an empty array. See also Array#last
for the opposite effect.
a = [ "q", "r", "s", "t" ] a.first #=> "q" a.first(2) #=> ["q", "r"]
Returns the last element(s) of self
. If the array is empty, the first form returns nil
.
See also Array#first
for the opposite effect.
a = [ "w", "x", "y", "z" ] a.last #=> "z" a.last(2) #=> ["y", "z"]
